[QUOTE="Deleted member 46119, post: 873331"] Oh yeah, for the 'lead only crowd'. Sorry I disagree.... Because I live in Crazyfornia, I did the work to figure out lead vs non-lead (copper). The biggest thing I believe is to over stabilize you bullet. Using [url=http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi]JBM - Calculations - Stability[/url] JBM Ballistics, lead is fine at anything over 1.3 but 1.5 seems to be better. For copper, we had problems under 1.5 getting up higher is better. My own 270Wby load (12 twist, not the modern 10 twist) became pinpoint accurate when I switched to 95 TTSX. The stabilization number from JBM is 2.032. 110's are OK too but not as good for me. Either one is 1000LB of force at 450 yards. Plenty for anything I will use that rifle for (until it becomes a 338 Edge). [/QUOTE]
